FIG. 1 is a front, right, and top perspective view of a semiconductorsubstrate showing our new design;

FIG. 2 is a front view thereof, a rear view being a mirror imagethereof;

FIG. 3 is a top plan view thereof;

FIG. 4 is a bottom plan view thereof;

FIG. 5 is a right-side view thereof, a left side view being a mirrorimage thereof;
